AUGUSTUS M. FREEMAN, OF OCEAN GROVE, NEW JEnsEY, assrenon TO HIMSELF ANDJOHN I. HOLLY, OF NEW YORK, N. Y.

BLIND SLAT FASTENING.

SPECIFICATION forming part of Letters Patent No. 319,087, dated June 2,1885.

Application filed March 21, 1885. (No model.)

To CLZZ whom, it may concern:

Be it known that I, AUGUSTUS M. MAN, of Ocean Grove, in the county ofMonmouth and State of New Jersey, have invented a new and usefulImprovement in Blind- Slat Fastenings; and the following is declared tobe a description of the same.

Blind-slat fastenings adapted to lock the slats when closed and to holdthe slats en- 10 tirely or partially open have been made heretofore; andthe obj ectof my present invention is to accomplish the same end but byanew and useful device. I employ a flat metal plate of a peculiar shape,and there are slots ber 5 tween projections upon one edge thereof, andsaid plate is pivotally connected to the inner surface of theblind-frame by a screw and cup or socket. There are lugs upon the upperend of the plate, and between them a swing- 2o ing tumblerlock ispivoted. This tumblerlock is adapted to being turned or swung down whenthe slats are closed, its edge bearing against one of the slats to lockthe same and the series to which it is connected, and said lock is to beturned back, and the plate moved when it is desired to wholly orpartially open the slats, in which case one slat of the series is madeto enter one of the notches formed upon the edge of the plate to holdthe slats in the 0 desired position.

In the drawings, Figure 1 is an elevation of part of ablind,with thefastening in the position it occupies when the slats are closed. Fig. 2is a side view of the fastening and section of 5 the blind; and Fig. 3is a view similar to Fig.

2, with the slats held open.

A represents the frame of the blind, and B the slats. a is a metalplate, preferably of malleable cast-iron. b and c are the slots formed40 between projections 1 2 3,1nade upon one edge of said plate c. Thereis a cup or socket, d,

covering the lower end of the plate a, and a screw, 4, passing throughsaid cup and plate into the blind'framaand forming a pivot for the platec. There are lugs, e, upon the upper end of the plate a, and to them theswinging tumbler-lock f is pivoted by pin 5.

The parts when not in use occupy the position shown in dotted lines,Fig. 1; but when it is desired to lock the slats closed the plate a ismoved into the position shown by full lines, Fig. 1, and thetumbler-lock f is turned into the position shown in Figs. 1 and 2, itsOuter edge coming in contact with the surface ot the closed slat,thereby locking the same, and the end of said tumbler-lock being heavyretains it in place against the slat.

\Vhen it is desired to wholly or partially open the slats B, the lock fis turned up, and the plate (0 moved back, and the edge of one slat ofthe series is inserted in either slot 1; or c,according to the desiredposition of the slats, and when so placed the slats are held rigidly inplace, and cannot be opened or closed by the action of the wind or bygravity.

This device is inexpensive and efficient,and can be readily applied tothe blind by any one.

I claim as my invention 1. In a blind-slat fastening, thecombinanation,with the plate (I, having slots 1' and c, of the cup orsocket (Z, to which the plate a is pivotally connected at its lower end,and the swinging tumbler-lock f upon its upper end, substantially asspecified.

2. In a blindslat fastening, the combina tion, with the plate a, havingthe slots 1) and c, of a screw for connecting said plate to thc blind,and a swinging tumbler-lock pivotally connected to the upper part ofplate an, ant adapted to being turned down to lock the slatssubstantially as specified.

Signed by me this 13th day of March ,A. D 1885.

AUGUSTUS M. FREEMAN.
